COMBINATION VALVE AND OIL-BURNER.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed September 12, 1918. Serial No. 253,792.

To all whom it may concern:

Be it known that I, Lns'rnn C. FRASER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented anew and useful Combination Valve and Oil-Burner, of which the following is a specification.

The device forming the subject matter of this application is adapted tobe employed for burning oil and one object of the invention is to improve the construction of the arch in the burner.

Another object of the invention is to improve the valve, whereby oil is supplied to the burner and drained backwardly from the burner.

Another object of the invention is to improve the means for holding the receptacle which receives the excess orwaste oil.

.It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description pro ceeds, the invention resides in the combination and arrangement of parts" and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the present invention, a portion of the receptacle being broken away; Fig. 2 is a longitudinal section taken 'throughthe burner; Fig. 3 is a longitudinal section taken through the valve; and Fig. 4 is a section taken approximately on the line 4-4of Fig. 1.

The device forming the subject matter of this application includes a burner comprising a bowl 1 having bosses 2 at its top, the bosses being supplied with passages 7. block 3 is provided, the same having a longitudinal bore 4, closed at one end by a screw plug 5 or otherwise. The block 3 is equipped with transverse passages 6 communicating with the longitudinal bore-4. Nipples 8 are right and left hand threaded into the passages.7 of the bowl -1 and the passages Got the block 3. i

In the-burners of the type mentioned,;.it

has been the practice heretofore so far as I am advised as to the state of the art, to connect with the bowl 1 an arch made out of a U-shaped piece of pipe. The bending oi this pipe into U-shape, makes it one of the Weakest parts of the burner, and a part which, in fact, deteriorates readily. One ob- ]ect of the invention is to improve the construction of the arch, and this is done by providing the block 3 and the nipples 8. The block 3 may be made simply and cheaply out of a stock piece of metal, by fashioning the bore 4 and the passages 6 and by closing up one end of the bore 4 through the instrumentality of the plug 5, a combustion orifice 100 being bored into the bottom of the block and communicating with the bore 4. The nipples 8 are standard parts which are always onhand in any steam fitters shop, and it will be seen that should occasion for renewing the arch arise, the arch may be renewed without difficulty. Further, owing to the specific construction of the arch, the same will withstand the destructive efi'ects of heat and will wear longer than an arch made from a bent piece of pipe.

. With the bottom of the bowl 1 is connected a conduit denoted generally by the numeral 9 and including an elbow 10 and a pipe 11 of any desired length. The pipe 11 is connected with one end of a valve casing 12, there being a fuel supply pipe 14 connected with the opposite end of the valve cas- The valve casing 12 has a main bore 15 which forms a communication between the pipes 14 and 9. In the interior of the valve casing 12 and about mid-way between the ends of the main bore 15, there is fashioned a. seat 16 adapted to receive the pointed end of a needle valve 17 threaded into the valve casing 12. When the needle valve 17 is engaged with the seat16, the main bore 15 is closed, but the needle valve may be raised, so as to open the bore 16. a

A chamber 18 is formed in the lower end of the valve casing 12, the upper end of a valve 19 being slidably received in the chamber. The second valve19 has a longitudinal passage 20, and there is an auxiliary bore 21 in the casing 12 leading fromv the main bore 15 to the chamber 18. .It is to be observed, however, that the auriiliary bore 21 is offset from the passage 20 in thesecond valve 19, so that when the second valve is thrust upwardly to a seat, the valve closes the bore 21. The second valve 19 is supplied with a circumscribing flange 22 disposed below the lower end of the valve casing 12.

The numeral 23 denotes, generally, a receptacle holder, including a neck 2% threaded at on the lower portion of the valve casing 12; The receptacle holder 23 comprises a cup-shaped body 26 which may be milled circumferentially, as shown at 36, to facilitate the rotation of the neck 24 of the receptacle holder on the lower portion of the valve casing 12. In the top of the receptacle holder 23, an opening 27 is fashioned, this opening being slightly smaller in diameter thanthe internal diameter of the neck 24. Consequently, a portion of the top of the body of the receptacle holder forms a shoulder 28, adapted to coact with the flange 22 of the second valve 1.9 in a manner which will be set forth hereinafter. In the side wall of the body 26 of the receptacle holder 23, slots 29 are formed, the same defining a bottom ring 30, connected with the body portion of the receptacle holder by means of reduced uprights 31. The invention comprises a receptacle grip 32 of resilient construction, including a triangular part 33, engaged about the uprights 31 and extended into the slots 29, the said part terminating in approximately parallel arms 34, which may be of any desired length. The upper end of a receptacle 35, which may be an ordinary milk bottle, may be inserted into the bottom of the body 26, the triangular part 33 of the grip 32 being expanded by means of the arms 34 to permit the upward passage of the top of the receptacle, the part 33 contraeting, to grip the receptacle and to hold the same in place in a manner which will be understood cle'arly when Fig. 1 is compared with Fig. 4.

Let it be supposed that the deviceis in use, and that a flame is proceeding from the burner orifice 100. Under such eir'cu'm stances, the neck 24 of the receptacle holder is threaded upwardly on the lower portion of the valve casing 12 until the shoul der 28 engagesthe flange 22 of the second valve 19 and thrusts the second valve up wardly, until itsupper end is seated against the valve casing 12 at the upper end ofthe chamber 18. Thus, the auxiliary bore 21 is closed. The needle valve 17 is'raised to open the main b'o re l5, and oil will flow frdm the pipe 14, throughthe main bore 15 and through the conduit 9 to the bowl 1 of the burner, the 'op'eranonpr a burner of the type shown in 2bfeing under stood clearly by those skilled in the Let it be supposed, however, that it is desired to drain the bowl l' o foil. Then, the first valve 17 is moved downwardly into the seat 16, closingthe mai-n bore l5 and portion of the valve casing 12, the bindcutting off the passage of oil to the burner from the supply pipe 141-. The receptacle holder is rotated, and the threaded neck 24 thereoi moves downwardly on the lower iug action 01' the shoulder 28 on the flange 22 of the second. valve 19 being relea sod, and the second valve 19 moving downwardly, until the upper end of the said valve no longer forms a closure for the auxiliary bore 21. The oil which is in the pipe 9 and the bowl 1 will then drain backwardly into the bore 15 at the right hand side of the first valve 17 Fig. 3), and will flow through the auxiliary bore 21, into the chamber 18, through the passage 20 in the second valve 19 and into the receptacle 35. The receptacle holder 23 may be rotated by gripping the milled part 36 of the body 26 but it will be found exceedingly convenient to rotate the receptacle holder by grasping the arms 3410f the grip 32.

The advantages arising out'ot draining the pipe 11 and the bowl 1 are many. For instance, when the valve 17 is closed, the valve 19 may be permitted to move downwardly, thereby draining away the oil, as aforesaid and extinguishing immediately, the flame at the combustion. orifice 100. Further it is desirable to drain the burner in order to clean the same, and for many other purposes which will suggest themselves to the user.

Having thus described the invention, what is claimed is':

1. Ina device of the class described, a bowl having passages; a block having a lon gitudina'l bore extended part-way through the block from one end thereof, the block having transverse passages communicating with the bore; pipe nipples right and left hand threaded into the passages of the bowl and the block; a removable closure for one end of the bore and mounted in the'block; a conduit leading from thebowl; and a 110 valve in the conduit. p
